CLOTH-CLEANING ATTACHMENT FOR FLOUR-BOLTS, 800.

SPECIFICATION forming part of Letters Patent No. 740,806, dated October 6, 1903. Application filed October 11,1902. Serial No. 126,929. (No model.)

To all whom it may concern:

Be it known that 1, JOHN CHARLES, a citizen of the United States, residing at Charlton, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Cloth- Cleaning Attachments for Flour-Bolts, &c., of which the fol- The object of my invention is to provide improved means for brushing the cloth of flour-bolts, and to that end I have invented and constructed a novel and useful attach-' tory motion are well known I deem it suits cientin the accompanying drawings, forming a part of this specification, to simply show an arrangement of bolting-boxes one above the other for illustrating one adaptation of my invention.

The invention consists of peculiar brushing means adapted to clean the cloth of flourbolts and other sieves utilizing gyratory movement of two separate parts of the matation and use of my invention fully underchine for effecting the operation thereof.

The invention consists, further, in the spee cial construction, arrangement, and combination of parts hereinafter described in detail, with the novel features thereofpointedout in the subjoined claims. I

In the drawings, Figure 1 is a vertical sectional view through an arrangement of flourbolting boxes, part broken away, showing my invention in use. Fig. 2 is an inverted or bottom plan view of the parts shown in Fig. 1 with one member broken away, showing my peculiar brush-operating means with arrows and a dotted circle indicating their movement; and Fig. 3 is a top plan view of the same arrangement of bolting-boxes with the covers of the upper boxes removed and the bottom of one box broken away, showing given.

I have heretofore stated that this invention 7 is not directed to any particular bolting apparatus or sieves, and consequently it becomes necessary in describing it to say that the invention is adapted only to bolting apparatus or sieve-machines in which two independent parts thereof have difierential gyratory motions. These parts may consist of a single sieve-box or aplurality thereof arranged and supported by devices common with all such apparatus or machines having gyratory motion, and therefore I will briefly refer to the parts thereof necessary to a full understanding of my invention.

In Figs. 1 and 2 of my drawings, A indicates a suitable base-board supported by upright arms B of any well-known character adapted by common means to impart a gymtory motion.

C denotes sieve or bolting boxes having a similar motion, but differential with the motion of the base-board A. The upper boxes D, arranged at right angle withthe boxes 0,

I by Well-known means and that they have gyratory motions difiering in movement.

The above statement will render the adaption of the several features employed by me and the operation thereof.

In carrying out my invention I fixedly secure to the upper side of the base-board A a circular block E. On the under side of the sieve-boxes C, I arrange a pulley-wheel F, fixed to the lower end of a vertical shaft G, extending into the sieve-box, asshown in Fig. 1-. The pulley'F and the block E may vary in size according to the movement to be The upper end of the shaft G has fixed thereto a crank-arm H, having its angular end loosely connected about midway of an elongated brush I, arranged to operate on the under side of the sieve-cloth J.

When I say sieve-cloth or sieve, I would be understood to refer to any character thereof, such as bolting-cloth or any type of screen.

The brush I is adjustably held up against the'sieve-cloth J by transverse eccentricallysupported bars K in the sieve-box. The bars K have handles L, located on the outside of sieve-box. (See Figsrl and 3.)

M denotes a belt extending around the cir-v cular block E and the pulley F. The ends of this belt M may be connected by a yielding coupling N.

In operation with the parts above described it is apparent that the fixed block E and the shaft G will describe a circle, as indicated at 0, Fig. 2, one around the other, so to speak, and during such movement of the parts, the block E being fixed or stationary on the baseboard A, obviously the belt M will impart a rotary motion to the pulley F in direction opposite to the planetary movement of parts E and F, (indicated by the arrow and dotted circle 0.) Now with a pulley F a little different in size compared with the block E a very slow rotary motion will be imparted to shaft G, crank H, and the brush I. The latter should be as long as possible consistent with the movement imparted thereto by the crank H, and being longer than the width of the sieve-box the sides of the latter Will guide it to effectively brush and keep open the meshes of the sieve.

I have heretofore referred to upper sieveboxes (indicated at D) arranged at right angle with the lower sieve-boxes. I have further stated that the upper sieve-boxes have a motion similar to the lower boxes and that the motion of the several tiers thereof is in different directions, being supported by arms and hangers common and well known in machines of similar character.

It being desirable to arrange brushes in the upper sieve-boxes I employa crank H and brush 1', supported by eccentric bars K, adapted to operate against the under side of the sieve J, all like similar features in the lower box 0. The crank supporting-shaft G, with the upper boxes D, has a gear-wheel P on its lower end meshing with a similar but intermediate gear Q, supported on the under side of the box, as shown, and in mesh with the gear-wheel R on a vertical shaft S, supported by hangers or suitable bearings T, fixed to the outer side wall-of the sieve-box, as shown in Fig. 1. The shaft S is driven by a belt M, pulley-wheel F, and fixed block E, all like similar features under the lower sieve-box C. It will be noticed in this connection that the block E is supported by and fixed to the upper side of the lower sieve-box C. Now the upper and lower sieve-boxes having in operation the differential gyratory motion above described it is apparent that the block E and the pulley F will be given may be arranged in each box adapted to clean two or more sieve-cloths. In Fig. 1 I show the shaft S broken off; but the same may extend up along the side of the box and connect with and operate devices similar to those driving the crank-shaft G.

Obviously the mechanism above described may be variously modified without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. The combination in a sieve-machine of the character stated,separate sieve-boxes havingdifferential gyratory movement, means for supporting the said boxes, brushing apparatus in each box adapted to operate against the sieve-cloth therein, connecting means on the outside of the sieve-boxes whereby rotary motion is imparted to the said brushing apparatus, deriving power effected through movement of the sieve-boxes, substantially as described.

2. In combination with a sieve-machine, of the character stated, an elongated sieve-box, a brush within the sieve-box longer than a cross-section thereof and adapted to operate against the sieve-cloth therein, a shaft having at one end a crank-arm connecting the said brush and at its other end revoluble means driven by a belt, the latter being connected with a separate part of the machine and deriving power through motion imparted to the sieve-box, substantially as described.

3. The combination with flour bolting or sieving machines, bolting or sieving boxes arranged at right angle one with the other and supported by hangers and suitable arms, in operation, imparting motion to the said boxes, brushes within the bolting or sieving boxes longer than a cross-section of its box, a crank-arm operatively connected with the said brushes, means within the said boxes adapted to provide support for the ends of the brushes, a suitable shaft connecting the said crank-arm and revoluble means at its lower end, a fixed block upon each lower box, and a drive-belt connecting the said fixed block with the revoluble means at the lower end of the said shaft, substantially as described.

JOHN CHARLES.
